Abstract
Large-bore suction overtube apparatuses including an inner lumen that is configured to receive an endoscope and to apply suction around the endoscope in order to remove material from within a body. In some cases the endoscope is removed, and in other cases removal of the endoscope is not required. Also described herein are methods.
Claims21
A method of removing material from the body of a patient, the method comprising:
- positioning a distal end of a rigidizing overtube adjacent to the material with an endoscope extending distally from distal end, wherein the rigidizing overtube concentrically surrounds a length of the endoscope so that the overtube and endoscope form an annular lumen;
- retracting a distal end of the endoscope proximally into a distal end region of the rigidizing overtube;
- and applying suction through the annular lumen to aspirate the material into the annular lumen and around the endoscope.
A method of removing a material from the body of a patient, the method comprising:
- positioning a distal end of an endoscope adjacent to the material;
- positioning a distal end of an overtube extending over the endoscope adjacent to the distal end of the distal end of endoscope with the overtube in a flexible configuration so that the endoscope transitions from an extended configuration extending distal to the overtube to a retracted configuration, wherein the endoscope distal end is recessed within the distal end region of the overtube, so that the overtube concentrically surrounds the endoscope forming an annular lumen;
- converting the overtube from the flexible configuration to a more rigid configuration;
- and
- applying suction through the annular lumen to aspirate the material into the annular lumen and around the endoscope.
A method of removing a material from the body of a patient, the method comprising:
- positioning a distal end of an endoscope adjacent to the material;
- advancing a distal end of an overtube distally over the endoscope so that the distal end of the overtube is adjacent to the material while the overtube is in a flexible configuration, and positioning the distal end of the endoscope within a distal end region of the overtube to allow visualization out of the distal end of the overtube by the endoscope, so that the overtube concentrically surrounds the endoscope forming an annular lumen;
- converting the overtube from the flexible configuration to a more rigid configuration;
- and
- applying suction through the annular lumen to aspirate the material into the annular lumen and around the endoscope.
